The mechanism of action of hydrazine hydrate in boiler deoxygenation
Thread Content
We know that the water used in high-pressure boilers must be deoxygenated. One of them is to add hydrazine hydrate to deoxidize. I would like to ask a layman's question. Does hydrazine hydrate directly react with the oxygen in the water, or does hydrazine hydrate reduce the iron to ferric oxide after the iron absorbs oxygen and corrodes to form ferric iron? This means that iron is the medium for the reaction between hydrazine hydrate and oxygen.
I think it reacts with oxygen in the water: N2H4+O2=2H2O+N2
